Abstract
The utility model relates to an oil pressure cutter cylinder. The cutter cylinder comprises a cylinder body, an upper cover, an oil pressure cylinder, a cutter screw and a main shaft. The oil pressure cylinder is arranged in the cylinder body, the cylinder body is covered by the upper cover, the cutter screw is fixed in the middle of the oil pressure cylinder, and one end of the cutter screw extends out of the oil pressure cylinder and the upper cover so that products can be processed. The other end of the cutter screw is fixed on the main shaft so that the main shaft, the oil pressure cylinder and the cutter screw form a firm integral structure and cutter control is facilitated. By the aid of the above structure, the top and the bottom of a piston of the oil pressure cylinder are uniformly stressed, the oil pressure cutter cylinder is high in motion force, and service life of the cutter cylinder is improved.
Description
Technical field
The utility model relates to machining, says so exactly to be used for the knife striking cylinder that machining is used.
Background technology
Knife striking cylinder is a kind of reinforcement gas-liquid conversion equipment, and compressed air acts on cylinder piston, produces thrust, promotes oil cylinder piston, makes the oil pressure that is higher than the compressed air several times act on depression bar, produces thrust, realizes the action of mechanical device.The knife striking cylinder main application be used for machining center lathe, CNC milling machine cutter automatically or the main shaft of automanual switchboard structure forge a knife, also can be used as the clamping device of anchor clamps and other mechanisms.
Existing knife striking cylinder, its cylinder is arranged with middle pull bar branch, makes between cylinder and the pull bar to have certain clearance; The buffering in when motion will be caused in this gap, the control that can reduce to forge a knife, and if control bad; Also can damage main shaft, influence processing.
Summary of the invention
Therefore, the purpose of the utility model provides a kind of oil pressure knife striking cylinder, and this knife striking cylinder can make oil cylinder piston evenly stressed up and down, and the motion dynamics is powerful, long service life.
Another purpose of the utility model provides a kind of oil pressure knife striking cylinder, and this knife striking cylinder is firm in structure stable, and is solid reliable, can control spacing effectively.
For achieving the above object, the utility model is to realize like this.
A kind of oil pressure knife striking cylinder; Said knife striking cylinder includes cylinder body, loam cake, oil hydraulic cylinder, the screw of forging a knife, main shaft; It is characterized in that being provided with in the cylinder body oil hydraulic cylinder, said loam cake is covered on the cylinder body, and the screw of forging a knife is fixed in the middle of the oil hydraulic cylinder; One end stretches out in outside oil hydraulic cylinder and the loam cake, to carry out the processing of product; And the other end of the said screw of forging a knife is fixed on the said main shaft, makes main shaft, oil hydraulic cylinder and the screw of forging a knife form firm integrative-structure, the control of being convenient to forge a knife; Such structure also makes on the oil hydraulic cylinder piston lower stress even, and the motion dynamics is powerful, has improved the service life of knife striking cylinder.
The said screw and main shaft is horizontal is fixed together of forging a knife, a kind of better mode is that forge a knife screw and main shaft is end to end, horizontal fixed makes the motion dynamics of forging a knife stable, powerful together.
The said screw of forging a knife is connected on the main shaft of fixed position with main shaft, is arranged with the main shaft fixed block of forging a knife, and the forge a knife outside of fixed block of main shaft is arranged with the fixed block of forging a knife that floats again, with screw and the main shaft of can stably fixedly forging a knife.
The said screw of forging a knife is provided with limited block, and limited block is positioned at the outside of cylinder body, is convenient to carry out in the course of the work the control of stroke.
The utility model adopts this structure, and main shaft, oil hydraulic cylinder and the screw of forging a knife form firm integrative-structure, and the control of being convenient to forge a knife has ensured the stability of processing; And this structure also makes on the oil hydraulic cylinder piston lower stress even, and the motion dynamics is powerful, has improved the service life of knife striking cylinder.
Description of drawings
The structural representation that Fig. 1 implements for the utility model.
The specific embodiment
Shown in accompanying drawing, the practical implementation of the utility model is elaborated.
As shown in Figure 1, the utility model is embodied as a kind of oil pressure knife striking cylinder, and this knife striking cylinder includes cylinder body 7, loam cake 1, oil hydraulic cylinder 4, spring 8, forge a knife screw 3 and main shaft 12.Be provided with oil hydraulic cylinder 4 in the cylinder body 7, loam cake 1 is covered on the cylinder body 7, and spring 8 is positioned at cylinder body 7, is held in oil hydraulic cylinder 4; The screw 3 of forging a knife is fixed and is passed in the middle of the oil hydraulic cylinder 4, and an end stretches out in outside oil hydraulic cylinder 4 and the loam cake 1, and this end that stretches out is provided with limit switch 2, in order to the stroke of the screw 3 of forging a knife now.Oil hydraulic cylinder 4 is provided with sealing ring 6 with the contact site of cylinder body 7, to realize the sealing of cylinder body 7.
Wherein, the screw 3 of forging a knife is end to end with main shaft 12, and horizontal fixed makes the motion dynamics of forging a knife stable, powerful together.
Be connected on the main shaft of fixed position with main shaft 12 at the screw 3 of forging a knife, be arranged with the main shaft fixed block 10 of forging a knife, the forge a knife outside of fixed block 10 of main shaft is arranged with the fixed block 9 of forging a knife that floats again, with fixed main shaft 12 stably.Be equiped with dish type shell fragment 11 in the main shaft 12.
The utility model makes main shaft, oil hydraulic cylinder and the screw of forging a knife form firm integrative-structure, and the control of being convenient to forge a knife has ensured the stability of processing.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
